changing Visibility to hosted winForms element in wpf application -

I have ReportViewer winForms control to show Microsoft reports in my WPF application hosted on my Windows platform. When the mousedown event of my text is triggered, I want to dim it, say 0 to 100 visibility, like some other element in my window Not so, so I was thinking that this is one or a specific for all hosted controls and how can this be solved?

Regards,

WindowsFormsHost Transparency Support But some WinForms do not control.

See the article on MSDN. First line in the "Behavior" table in particular:

Some Windows form controls do not support transparency For example, text box and combo box controls will not be transparent if hosted by WPF.
